IMPROVEMENT IN MlLK-COOLERS.

Specification forming part of Letters Patent No. 164,048, dated June 1,18 5; application filed March 30, 1875.

To all whom it may concern:

Be it known that I, R ssELL SMITH, of Richford, in the county ofFranklin and State of Vermont, have invented a new and valuableImprovement in Milk-Coolers; and I do hereby declare that the followingis a full, clear, and exact description of the construction andoperation of the same, reference being bad to the annexed drawings,making apart of this specification, and to the letters and figures ofreference marked thereon.

Figure 1 of thedrawing is a representation of a plan view of mymilk-cooler. Fig. 2 is a longitudinal vertical sectional view of thesame, and Fig. 3 is a transverse vertical sectional new.

The object of this invention is to improve the milk-cooling apparatusfor which Letters Patent of the United States were granted to me on the24th day of November, 1874; and the nature of my invention consistsmainly in a continuous pipe having an upright centrallydivided trunk,which is provided with a watersupply funnel and an overflowdischarge-pipe, whereby water poured into the funnel will make thecircuit of the said continuous pipe, and be discharged from theoverflow-pipe, as will be hereinafter explained.

In the annexed drawings, A designates a.

supporting-frame, on which my improved pan rests by its ledges a. In aplan view the pan B is rectangular, and in a cross-section takenvertically it has a rounded bottomthat is to say, its bottom and sidesare of one piece of sheet metal without angles, and the bottom isinclined longitudinally, and provided at its lowest point with a draw-0Epipe, b, in which is a removable plug, 0. The cooler C is formed oflongitudinal and transverse pipes communicating with each other, whichpipes are triangular in cross-section. From the middle of the length ofone of the transverse pipes of the cooler rises a trunk, D, which iscenarally divided by a vertical partition, 0, which also divides thespace in said transverse pipe, as shown in Fig. 3. I thus form in trunkD an inflowpassage, f, having a funnel, g, and an air-hole, t, at itsupper end, and an outflow-passage,f", is also formed, provided with anangular discharge-pipe, h. One end of the cooler O is supported by meansof legs is upon the bottom of the pan B, and the other end of the cooleris supported upon the edge of the pan B by means of the angulardischarge-pipe h.

It will be seen from the above description that water poured into thefunnel y will circulate through the pipes of the cooler, and flow outthrough the pipe h. The hole i admits air, and allows the water to flowfreely through the funnel without liability of overflowing at thispoint.

WhatI claim as new, and desire to secure by Letters Patent, is-- v Therectangular cooler 0, formed of triangular pipes, in combination withthe centrallydivided trunk D, having a feed-funnel, g, and air-hole i,and an angular discharge-pipe, h, substantially as described.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.
